Laboratory automation is one of the development trends of laboratory medicine, especially in the process of medical and health system reform in China, based on the establishment of universal medical security system, a large number of medical needs were released, patients increased, the specimen increased, Lab Automation laboratory automation can adapt to this Of the demand, so the past two years, large domestic hospitals have introduced a fully automated assembly line.

Refers to the different analytical instruments and analysis before and after the sample system through the automation and information network connection. LAS usually contains a sample before and after processing unit, analysis unit, sample transport system and support the operation of the unit software systems and laboratory information systems. LAS is customarily divided into total laboratory automation (TLA) and modular automation (MLA) systems.

The characteristics of laboratory automation

The ideal LAS should have the following characteristics: ① openness: not limited to only a manufacturer of equipment connected, should be able to connect with any other manufacturers of the analyzer; ② integrity: a complete "pre-analysis - Analysis of "hardware and software support, information system integrity; ③ flexibility: automatic system can be based on site requirements, a variety of places placed; ④ intelligence: highly intelligent, Lab Automation user-friendly system design, contribute to the successful completion of the experiment ; ⑤ independence: the functional units are mutually independent and relatively independent, Lab Automation the unit can operate independently. But to meet all the above conditions is still quite difficult. Therefore, LAS has a broad and narrow laboratory automation.

Laboratory automation is to connect a variety of analytical instruments and analysis of pre-processing equipment and analytical processing equipment to achieve automated blood collection, labeling, sorting, transportation, sample processing, analysis and storage. Constitute a pipeline operation, Lab Automation to achieve the automation of the inspection process, also known as the generalized laboratory automation system.

Laboratory automation definition and characteristics

Laboratory automation is one of the development trends of laboratory medicine, especially in the process of medical and health system reform in China, based on the establishment of universal medical security system, a large number of medical needs were released, patients increased, the specimen increased, Lab Automation laboratory automation can adapt to this Of the demand, so the past two years, large domestic hospitals have introduced a fully automated assembly line. First, the definition of laboratory automation, laboratory automation refers to the different analytical instruments and analysis before and after the sample system through the automation and information network connection. LAS usually contains a sample before and after processing unit, analysis unit, sample transport system and support the operation of the unit software systems and laboratory information systems. LAS is customarily divided into total laboratory automation (TLA) and modular automation (MLA) systems.

Laboratory automation is to connect a variety of analytical instruments and analysis of pre-processing equipment and analytical processing equipment to achieve automated blood collection, labeling, sorting, transportation, sample processing, analysis and storage. Constitute a pipeline operation, Lab Automation to achieve the automation of the inspection process, also known as the generalized laboratory automation system.

Since the time taken for manual sample treatment is more than 70% of the total testing process and is the main cause of reporting errors, the primary goal of laboratory automation is to minimize the number of steps that do not have value-added benefits throughout the analysis cycle, including samples Classification, opening, centrifugal, the sample into the analytical instruments and classified storage, that is, to achieve part of the sample pre-processing automation. The second goal of automation is to increase the available time of the value-added benefit step in the analysis cycle as much as possible so that the inspector has more time and effort to improve the quality of the test results. The step of value-added benefits includes the review of the risk results and decides whether to carry out re-examination or additional test items based on specific results. Lab Automation These functions can be automated in sample post-processing systems.

TLA consists of hardware and software components, hardware, including specimen processing and testing all the necessary equipment, the software is mainly the implementation of process control. According to the processing flow of the specimen, all the equipment can be divided into four main parts, Lab Automation namely the specimen pre-processing module, the detection pipeline, the independent detection unit and the specimen processing module.

(1) pre-treatment system: ① input classification: In the specimen processing module, the most important is the choice of blood collection, classification and specimen packaging, different TLA system processing in different ways. ② Centrifuge: The sample rack is automatically centrifuged in a centrifuge and re-placed in the conveyor. Whether it is in the assembly line or sample pretreatment system centrifuge is necessary, Lab Automation but also the most expensive. According to the economic strength and sample requirements, the pipeline can be configured 1 to 2 centrifuges, the rest of the line under the centrifugal, to solve the peak sample centrifugal problem. ③ off the cover: This is the most important biosafety, can automatically remove the lid of the sample tube into a dedicated recycling container. In order to avoid the different pieces of different ways to bring the complex structure of the mechanical device, in the choice of open capping machine must first unified blood collection standards, reduce the type of test tube. ④ sorting: should be based on the work of the laboratory selection.

(2) detection system: the detection line and the specimen pretreatment module is connected, the sample after pre-treatment directly into the pipeline. Biochemical, blood, immune and other analytical instruments connected to the pipeline, through the connection unit automatically load the sample.

Analysis: Biochemical analyzers need to consider the degree of openness of the channel, the higher the degree of openness, the higher the user's autonomy, but the use of open reagents to reduce costs at the same time, Lab Automation may pay a certain cost of quality loss. Therefore, should be in the purchase of equipment at the same time, access to cost-effective reagents.
